August 8, 20178 yr See attachment for details. Is what is shown in the attachment normal? I would suspect, because there are 2 drives, that raid 1 would be used; and so both drives should have identical writes/reads?
August 8, 20178 yr Author Maybe stupid.. but where can I find those settings? Attached dianostics! Thanks guys unraiddata-diagnostics-20170808-1624.zip Edited August 8, 20178 yr by robertoal
August 8, 20178 yr Community Expert You're using an older version that doesn't include btrfs pool info on the diagnostics, update to v6.3.5 and post new diags.
August 9, 20178 yr Author Thanks for the tip John, I attached the new diagnostics file! unraiddata-diagnostics-20170809-1101.zip
August 9, 20178 yr Community Expert The diagnostics confirm only one device (cache2) is being used, this should fix it: -Backup your cache in case something goes wrong -Stop the array -if you rebooted since check that cache1 is still sdf and wipe it using: blkdiscard /dev/sdf -on the WebGUI click on "Main", cache1 SSD icon should turn blue -start the array, a balance will begin and when all cache pool read/writes stop the pool should now be using both devices. You can post new diags to confirm if unsure.
August 16, 20178 yr Author Johhny thanks for your help again!! Check diagnostics i attached, looks like its working now! +1 Rep! unraiddata-diagnostics-20170816-1430.zip
August 16, 20178 yr Community Expert Both are being used now but it's not balanced correctly, on the main page click on "cache", then on "balance status" paste in the options: -dconvert=raid1 -mconvert=raid1 Then click on balance.
August 16, 20178 yr Author It is balancing now. thanks again! I am planning on getting in two more 160gb intel ssd's, especially for VM's the room I have now is not enough. Which options should I use then?
August 16, 20178 yr Community Expert With 4 devices you can use raid10, you get redundancy, capacity and better performance.
August 17, 20178 yr Author Johnie! In need of your help again..

August 17, 20178 yr Author Ok. Somehow it was unable to find sdh.. on which the data was located. Thank god I make backups :-) Now I just removed al partitions and let it recreate them. Think it works now although it still says 'no balance found' Is this allright?
